Released in 2002, this Main Game is a strategy and simulator where you build and manage intricate amusement parks. The core loop involves designing custom roller coasters and attractions, managing park finances, setting prices, hiring staff, and ensuring guest happiness across various scenarios. Its distinctive feature is the advanced, intuitive building tools that offer precise control over custom track design and thematic scenery integration.
The primary objective revolves around scenario completion, which ranges from building parks from scratch to taking over existing, sometimes struggling, locations. Success is measured by achieving specific financial goals, guest satisfaction ratings, and park prestige within set time limits. Players must balance the construction of various attractions—from gentle carousels to extreme thrill rides—with essential park infrastructure, including pathways, food stalls, restrooms, and scenery.
Management mechanics are robust, requiring careful attention to pricing, marketing, staff hiring and training (such as mechanics and janitors), and ride maintenance schedules. Keeping the park clean, ensuring paths are logically laid out, and monitoring guest happiness through feedback are crucial elements of maintaining profitability and growth.
A defining feature of this simulation is the unparalleled level of creative freedom, particularly concerning roller coaster design. The game provides advanced, intuitive building tools that allow players to construct custom tracks with precise control over elements like banking, vertical loops, corkscrews, and G-force management. Players can design the most gut-wrenching, custom-made coasters imaginable, test them for safety and excitement ratings, and then watch their park guests experience the creations.
Beyond the rides themselves, the game emphasizes thematic immersion. Players can select from a wide array of themes, including fantasy, science fiction, and adventure settings, applying these aesthetics to scenery, shops, and ride entrances. Furthermore, this iteration introduced the ability to import and utilize designs from real-world amusement parks, offering a unique layer of authenticity for simulation enthusiasts.
While the base game offers numerous scenarios and building options, its content depth is expanded through two official expansion packs, which introduce new rides, themes, and gameplay challenges.
The content of this game is suitable for all persons.

OpenRCT2 is an open-source re-implementation of RollerCoaster Tycoon 2 (RCT2), expanding the game with new features, fixing bugs and raising game limits. The gameplay revolves around building and maintaining an amusement park containing attractions, shops and facilities. The player must try to make a profit and maintain a good park reputation whilst keeping the guests happy. OpenRCT2 allows for both scenario and sandbox play. Scenarios require the player to complete a certain objective in a set time limit whilst sandbox allows the player to build a more flexible park with optionally no restrictions or finance.

Time Twister is the second expansion pack to the game RollerCoaster Tycoon 2, and is based on a time theme, exploring various time periods. The expansion pack offers many new themed rides, scenery items, and scenarios. Much like with Wacky Worlds, this pack was also criticized for its lack of new gameplay options or new rides, since the rides included in the expansion pack are merely re-designs of previously available rides.

Wacky Worlds is the first expansion pack for RollerCoaster Tycoon 2. The focus being on nations around the world, Wacky Worlds includes new scenarios, hundreds of new objects to use in your park.
